Bcm94360NG works great OOTB. No kexts or messing around.

Use drivers from the Fenvi site for windows.

I can confirm the BCM94360NG works out of the box. This is an M.2 card which can be swapped with the factory WiFi and fits in the I/O space.

It is not the fastest card with speeds around 300mbps. At this time it is the best available options.

Depending on which version of MacOS you are using SmallTree may not work for Ethernet. I can confirm that MacOS 12.1 and 12.2 Ethernet does not work. But MacOS 12.0 Beta 8 & 9 SmallTree does work.

Old? It was only a month ago. And, as it turns out, it’s been a productive month!

No one on this sub mentioned it, but I kept digging and found an L-shaped adapter for half-size PCIe to M.2 form factor.

That allowed me to order the most compatible card I felt would safely fit/work. Also had to order converter antennae. (I suggest buying a second pair of those, as they’re incredibly delicate but also inexpensive.)

Here are the Amazon links and a photo of the Frankenstein WiP. It all fits with no visible bulge, though you can almost feel something if you’re trying hard. It’s currently running Win 11 Pro Lite (for testing and prep). Oh, and I wrapped the antennae connections with electrical tape, which was after I took the photo.

Hope this helps. Keep me posted if you try this out yourself.
